Bulbs (exterior lights) -
renewal

2

1 Whenever a bulb is renewed, note the
following points.

a) Disconnect the battery negative lead

before starting work.

b) Remember that, if the light has just been

in use, the bulb may be extremely hot.

c) Always check the bulb contacts and

holder, ensuring that there is clean metal-
to metal contact between the bulb and its
live(s) and earth. Clean off any corrosion
or dirt before fitting a new bulb.

d) Wherever bayonet-type bulbs are fitted

(see Specifications), ensure that the live
contact(s) bear firmly against the bulb
contact.

e) Always ensure the new bulb is of the

correct rating, and that it is completely
clean before fitting it; this applies
particularly to headlight/foglight bulbs
(see below).

Headlight

2 Working in the engine compartment,
release the clip securing the cover to the rear
of the headlight unit. Withdraw the cover (see
illustration).

3 Disconnect the wiring plug from the rear of
the headlight bulb.
4 Release the spring clip securing the bulb in
the light unit, then withdraw the bulb (see
illustrations).
5 When handling the new bulb, use a tissue
or clean cloth, to avoid touching the glass
with the fingers; moisture and grease from the
skin can cause blackening and rapid failure of
this type of bulb. If the glass is accidentally
touched, wipe it clean using methylated spirit.
6 Install the new bulb, ensuring that it locates
correctly in the light unit. Secure the bulb in
position with the spring clip, and reconnect
the wiring plug.
7 Refit the cover to the rear of the light unit,
and secure with the clip.

Front sidelight

8 The sidelight bulb is located in the rear of
the headlight housing.

9 Working in the engine compartment,
release the clip securing the cover to the rear
of the headlight unit.
10 On models up to 1992, pull the bulbholder
from the rear of the headlight unit. On models
from 1993, it will be necessary to twist the
bulbholder through a quarter turn before it can
be removed (see illustration).
11 The bulb is a push-fit in the bulbholder
(see illustration).
12 Refitting is the reverse of the removal
procedure, ensuring that the bulbholder seal
is in good condition.
